I tested it with a voltmeter. Total volts was 8.01~8.03 but when doing each cell, balance port and negative/positive they read 4.02 on the negative and 3.99 on the positive. Not fully charged so that's a relief but odd the charger reading the total output at 7.85 but its really 8.01. I know this isn;t too far off but again my other batteries read either exactly the same or off by 0.01.
